For the past few months have been an ambitious proposal to replace FBCON with the user-space KMSCON as the default VT console starting on Fedora 44. Unfortunately, this and a few other features have now been delayed to the Fedora 45 release six months later...

A request for comments (RFC) patch series was posted today to the Linux kernel mailing list to introduce the AMD Dynamic Power and Thermal Configuration Interface "DPTCi" driver. With this driver it would provide better upstream Linux kernel support for tuning the power / performance / thermals of modern Ryzen-powered gaming handheld devices. Though don't get too excited right away as the driver was assembled in part by AI that is already causing a bit of a ruckus on the LKML due to lack of disclosure...

Google announced today that beginning later this year they are moving the Chrome web browser from its four week release cycle down to a two week release cadence...

Over the past month I have been running a lot of Linux benchmarks on Intel's new Panther Lake using the Core Ultra X7 358H and its Xe3-based Arc B390 Graphics. The Arc B390 on Linux has been quite interesting with its OpenGL and Vulkan graphics performance compared to prior generations of Intel graphics plus the Intel Compute Runtime / OpenCL performance too. In today's article are more benchmarks of the latter in looking at the Intel Rendering Toolkit and OpenVINO AI performance on the Xe3 B390 Panther Lake graphics compared to prior Lunar Lake and Meteor Lake.

There is two weeks to go until the GNOME 50 stable release while out today is the release candidate of Mutter 50. This Mutter 50.rc release brings some exciting last-minute enhancements to this Wayland compositor...

Germany's Sovereign Tech Agency announced a new and expanded Sovereign Tech Fellowship program that is now open to community managers and technical writers, beyond just FOSS maintainers from the prior round...

Apple announced today the new Fusion Architecture with the M5 Pro and M5 Max SoCs that also feature a next-generation GPU...

Last year AMD and Intel as part of the x86 Ecosystem Advisory Group announced ChkTag for x86 memory tagging across processors to better fight buffer overflows and use-after-free errors. In preparing for ChkTag with future processors, Intel has begun adapting their Linear Address Masking (LAM) support to more nicely jive with it...

Intel yesterday sent out their first "drm-xe-next" pull request to DRM-Next of new Xe kernel graphics driver improvements they have readied for their eventual upstreaming into the Linux 7.1 kernel...

AMD open-sourced the ROCprof Trace Decoder "rocprof-trace-decoder", a tool useful for developers targeting the AMD GPU compute stack...

A Linux driver has been published for the ARCTIC Fan Controller to be able to read fan speeds under Linux as well as setting the PWM fan speed for each of the ten fans supported by this controller. Making this driver all the more exciting is that ARCTIC Cooling is directly working on this driver rather than just being a community/third-party creation. Furthermore, ARCTIC Cooling is working on getting this driver to the upstream Linux kernel...

Ahead of the stable GIMP 3.2 release hopefully happening soon, GIMP 3.2 RC3 was released this evening for testing...

The AMD EPYC 9755 128-core Zen 5 server processor has been benchmarked a lot at Phoronix since the EPYC 9005 "Turin" launch as their top-end Zen 5 server processor with "full fat" cores compared to the denser Zen 5C cores that extend up to the EPYC 9965 at 192 cores. For those eyeing the 128 core per socket sweet spot, there is also the EPYC 9745 that is made up of 128 Zen 5C cores that allows for a 400 Watt TDP compared to the 500 Watt EPYC 9755. Today's benchmarking is comparing the EPYC 9745 and EPYC 9755 performance and power difference.

An important default kernel behavior change worth noting in advance for the upcoming Linux 7.1 kernel is that the system will attempt to power-off automatically if encountering any fatal ACPI errors. Up to now the Linux kernel has just logged ACPI fatal errors...

Last week with my ongoing testing of the in-development Linux 7.0 kernel I found nice performance improvements for PostgreSQL and other workloads when testing on a 128-core AMD EPYC 9755 "Turin" server. Curious if those wins were due to optimizations focused on better scalability with today's "big" servers, I also ran some comparison Linux 7.0 benchmarks on the smaller AMD EPYC 4005 class servers too. Some nice wins carried over...

Work is underway by 9elements on porting Coreboot plus AMD openSIL to the first-generation Ryzen 7000 series Framework 16 laptop and is expected to be followed by a similar port to the Framework 13 Gen1 laptop too...

Zlib-rs as the Rust programming language implementation of Zlib from the Trifetca Tech Foundation is out with a shiny new release (actually, releases) today...

ASUS desktop motherboards have been seeing broader sensor monitoring support on Linux in recent years. ASUS motherboards for Intel and AMD processors have been seeing more support added thanks to the open-source community with new additions to the likes of the ASUS-EC-Sensors driver and other hardware monitoring (HWMON) driver code. This is continuing for Linux 7.1...

Armbian 26.02 has been released released for this Debian-derived Linux distribution primarily focused on supporting a range of Arm and RISC-V platforms. With Armbian 26.02 there is yet more new boards added while moving to the Linux 6.18 LTS kernel and also adding a RISC-V Xfce desktop install option...

Intel kicked off the new month by releasing the latest version of LLM Scaler vLLM (llm-scaler-vllm) as their Docker-based solution for running vLLM on Intel Battlemage GPUs for AI inferencing...
